I subscribe to a freecycle group for our area. For those unfamiliar with the concept, freecycle is basically where you post the junk you're giving away in the hopes that someone will peruse the page and decide they need it. It's kinda like a trailer trash version of craigslist.
Sometimes the postings get a little surreal. I have seen people posts requests for beds, cars, outbuildings, and even houses, expecting other people to just hand them over. But our freecycle group is fairly inactive, with the most frequent posts coming from the lady with the most fertile cats on the planet posting ads for free kittens on a regular basis.
This begs the question: why would anybody actually pay for a cat anyway? Sure, you'd pay for shots, spaying, and neutering, etc, but actually paying for a cat seems nonsensical, except in the rare instances where you are looking for a specific breed. With the proliferation of cats out there, it seems the idea of actually purchasing one is a fairly ludicrous proposition.
